Belift: known that 1, Homes C. GARDNER, citizen of the'United States,

i and State'of have vinvented certain new an @Liquid State; of which the following is a My invention relates to reference being had'to the acdrawings;

1 My improved apparatus provides for the Iota-rapid circulation of the condensed whileexposed to a 1 A, g I r I I I I cooling medium, and at the same time for the in esl s- 'd iis ga w h P0 1 of the incoming unconthe liqu d ulting from condensation, in such manner to ital'ze advantage of condensing r apparatus and promoting lique- "action of a cooling faction. "In the operationof the apparatus the uncondensed gases are subjected to the medium so as to effect condensation thereof to'a greateror less ex K bein allowed .to pass out 'j' while the separated and partly lique tent, the uncondensed gases being then sepa-' rated from the resulting liquid,.-the liquld of the apparatus gases are furtherfic'ooled lied and then intermingled with: the incoming gases. *By'this procedure f the incoming, 7 hot gases 'relatively large volume gases and also with a portion of the liquid.

while permitting anyfiuncondensed" gases; to a riser" 13, which connects 12, as-sh0wn in Fig.

relatively uni as to form a circuitous line'of substantially the same verr elevation, some of ft he, 7 being in 580M011; and Flg. 2fis'an e'nd f i to the drawings- 3 indicates a 8'0 f cold 1 mgs I have shown a series oftrou'ghsiiarby the pipe 6 iurther exposed to the'con pipes 5. willfbeuiim s we be is e b I with; the} next higher pipe densing action. of the cooling water, as said pipeextends under the mam body of the coil beforereaching the outlet 7, so that the cooling water flows over it; thus the sep arated liquid is delivered at acomparatively low temperature.

which in turn connects with the uppermost pipe and with a pipe16 immediately below it. The uppermost pipe 15 is intended to receive and conduct away any uncondensable gases,'-and to that .end is provided with a discharge pipe 17, having a valve 18, as shown in Fig.1. The pipe 16 receives the condensable gases delivered to it through the riser 13. By providing the pipe 15 aboveand communicating with the pipe 16 between the latterpipe and the riser 13, the un'condensable gases, mixed with a greater or less proportion of condensable gases, pass into and accumulate in said pipe 15 where they are further cooled by the cooling water,

before flowing smce said pipe'extends under the trough 4:, above the main bddy of the coil. Thus any co'ndensable ga'sesin thepipe 15 are condensed and the'li quidproduced flows down into the pipe. '16 and thence down through the balance of "the coil. This construction is advantageous {in that it provides for the separation and cooling of the uncondensable gases and their accumulation in such manner that-they-may readily be blown out from time to time, as desired, by opening the valve 18, without interfering with the operation of the condenser as a whole.

' 19 indicates the supply pipe through which the gases to be condensed are delivered to the coil, said pipe having a series of -1 ectors 20, one for each coil, each of which injectors is controlled by a valve 21.. The several injectors open into their respective coils at a point a short distance below the uppermost member 16 of such coils, so that the hot gases are not introduced into the coils at the top, but at an intermediate point thereof, whereby a portion of the coil lies above the point of introduction of the gases, and a portion below such point. It will be observed that the cold water used for condensing purposes passes over that portion of the coil over the remainder of the coil, so that the 13 to the uppermost members of the coil are subjected to the coldestwater, thuspromoting their partial liquefaction. It will be notedalso that the liquid formed in the uppermost members of the coil flows, with the gas stream, down to the point Where they meet the incoming gases, and they are there intermingled with such gases, with the re sults previously mentioned. The gases are injected under pressure, which also applies suction to those members of the coil lying above the injector,

The riser 13 connects at' I its upper end with a branched bend 14,

which lies above the injector gases delivered by the riserand it is designed in "practice to operate the apparatus in such manner that the volume of uncondensed gases drawn up through the riser 13 1s equal to that injected, thus provldlng for a rapid circulation ofthe gases through the system, thereby greatly increasing the capacity and efficiency of the condenser. v
